Why browser-based matters

A browser workflow avoids installing desktop software while still keeping the media processing path local to your device.

What still needs the network

Initial app loading, model downloads, licensing flows, and analytics can use the network. The transcription media itself is processed locally.

Recommended workflow

  1. Open OfflineTranscriber and select your local audio or video file.
  2. Wait for model setup if this is the first run in the browser.
  3. Run transcription locally and keep the tab active while processing.
  4. Review the transcript and export TXT, SRT, VTT, or JSON when available.

FAQ

Can this run without uploading recordings?

Yes. The normal transcription workflow processes media locally in the browser and avoids uploading raw files to our app backend.

What should I check before using it offline?

Load the app and model once while online, then keep the same browser profile and site data so cached assets remain available.

What are the main limits?

Large files depend on local memory and compute. Source quality, speaker overlap, and browser support affect speed and transcript accuracy.
